The only thing I could do, would be to setup a set of virtual machines locally on my laptop. But I'm to lazy to do this, since I'd have to build a local network between the VMs and it's actually useless since all is on my laptop.
This is childish. You asked how to get started
But I did not ask how to get started with *installing* x2go (with no root access to the server it's not possible anyway), but rather I asked about how to get started *understanding the sources* -- some good overview documentation, since I would probably have to do something myself to make my wish happen.
But I understand. This is childish. :-(
However, might this change in a near future? Unless you fix it: Unlikely, as all active devs have root and lots of other stuff to do. :)
Well, maybe x2go is not the software I am looking for. :-(
